Transfer between verbal and algebraic descriptions. Pupils' strategies and problems
Novotná, Anežka ; Vondrová, Naďa (advisor) ; Roubíček, Filip (referee)
The aim of this thesis is to gain insight into the problems that pupils have when switching between verbal and algebraic expressions, through the analysis of their problem-solving processes. The work is divided into theoretical and experimental parts. The theoretical part of the paper contains three sections. The first describes the analysis of three selected Czech textbooks series for primary schools in terms of teaching the concept of variables and algebraic expressions. The next section deals with international comparative research TIMSS and the success of Czech pupils of year 8 in algebra. In the third section, results of international research concerning the issue of transition between verbal and algebraic expressions are described. The main part of the work is the experimental part, it aims to describe the difficulties encountered by pupils in algebra and to identify their likely sources. The basis for the own research was a set of 9 problems based on released TIMSS problems. The target group of pupils was year 9 of primary school, with whom the investigation was carried out via think-aloud interviews. First, a pilot study was conducted on a sample of 3 pupils, during which a set of test problems was checked. The main study involved 8 pupils. The think-aloud interviews were recorded and later...

Stability of the catalytic domain of neutral trehalase studied by differential scanning fluorimetry
Šmídová, Aneta ; Obšilová, Veronika (advisor) ; Kacířová, Miroslava (referee)
This bachelor thesis is part of a project aiming for the crystallization of trehalase domain of neutral trehalase Nth1 from Saccharomyces cerevisiae. The main goal of this thesis is to optimize the purification protocol of two different constructs of yeast Nth1 and determine the optimal buffer for crystallography of these constructs using the differential scanning fluorimetry DSF. Trehalases are important, highly conserved enzymes found in many organisms. These enzymes belong to the class of hydrolases, subgroup of glycosidases and their common feature is hydrolytic cleavage of trehalose molecule into two glucose subunits. Trehalose is a naturally occurring non-reducing disaccharide which serve in yeast cells as storage carbohydrate and energy and stress metabolite. Trehalose and its hydrolysis is very important in the life cycle of the insect, as it is present as the main sugar component of insect hemolymph, so some trehalase inhibitors could be used as insecticides. By this time, however, only one structure of trehalase from a prokaryotic organism Escherichia coli was solved. For this reason it is very important to solve the structure of trehalase from a eukaryotic organism. Keywords: Nth1, expresion, purification, DSF Key subjects: Protein biochemistry, biophysical chemistry

Perception and expression of non-verbal vulgarity in context of gender
Šorfová, Eva ; Smetáčková, Irena (advisor) ; Novotná, Hana (referee)
Vulgarity is becoming to be an increasingly discussed and interesting topic, although not deeply explored by science. This thesis includes a survey focused on vulgar gestures. The main objective is to compare differences in perception and expression of non verbal vulgarisms- gestures among 1) boys and girls 2) two different teenage groups, in terms of frequency, form and purpose of using the gestures. I mainly use a closed, semi-closed or open questions in the questionnaire, which also includes a parallel presentation of each gesture. A sample of respondents is composed of to groups of teenagers at the age of 1) 13 - 15 and 2) 16 - 17 - who are willing to participate. Powered by TCPDF (www.tcpdf.org)

Dance as a Religious Expression: History and Application in Christian Liturgy
Zídková, Veronika ; Kotas, Jan (advisor) ; Bravená, Noemi (referee)
The diploma thesis "Dance as a Manifestation of Devotion, its History and Use in the Christian Liturgy" enquires into the phenomenon of dance in the context of Christian culture. It outlines the development of the religious dance in the history of mankind, its forms and modes of perception in different cultures and religions. The thesis also deals with dance as an expression of faith in Jewish culture whence the Christian liturgical dance often drew inspiration and thus went back to its own roots. It seeks to explore the positive attitudes of believers towards dance, but also the mistrust that accompanied dance throughout the history of Christianity. Additionally, the paper presents the situation of dance in the contemporary Christian culture on different continents (Europe, America, Africa), to pursue finally the question of dance as a manifestation of devotion in the Czech Republic. Based on the collected material, the thesis seeks to present the deep potential of dance that make believers express through gestures and movements their respect to God, their joy and anxiety, grief and hope, and thus can, alongside music and singing, enrich the liturgy to a great extent. Keywords Dance, gesture, liturgy, prayer, expression.

Portraits of Ancestors
Burjanová, Zuzana ; Hůla, Zdenek (advisor) ; Daniel, Ladislav (referee)
a abstrakt vAJ Burjanová, Z.: Portraits of Ancestors [Diploma Thesis] Praha 2013 - Charles University, Faculty of Education, Art Education Department, 94 p. This thesis deals with a portrait and its significance for a present human. It treats different conceptions of our ancestors. A research sample about the way how people handle family photographs and how they perceive the heritage of their ancestors is an integral part of the thesis. Some fine arts problems were proposed resulting in finding the way how pupils of primary schools and students of secondary schools were able to cope with a human face illustration. Key words: Identity, expression, appearance, rootage, family, genetics, heritage Burjanová, Z.: Portraits of Ancestors [Diploma Thesis] Praha 2013 - Charles University, Faculty of Education, Art Education Department, 94 p. This thesis deals with a portrait and its significance for a present human. It considers the relation between paintings and photographs. It treats similarities and differences within a family. One of the topics are family photographs and their form. It analyses differences between digital and physical sources. It treats different conceptions of our ancestors (family concept, historical-family, historical-cultural and biological concepts). A research sample about the way...

Aesthetic Factor in John Dewey's Conception of an Experience Aesthetic Relevance demonstrated by Example of Snowbording
Vyhnánková, Klára ; Kaplický, Martin (advisor) ; Dadejík, Ondřej (referee)
This diploma thesis examines John Dewey's concept of experience, focusing especially on his notion that an aesthetic factor is present in every complete and consummatory experience. It deals with the differences between a common experience and "an experience" and examines how an aesthetic factor works in them. The indispensable role of the aesthetic factor is intentionally demonstrated on the non-artistic example of experiences of snowboarding. The most important findings are developed through the approach of Richard Shusterman's somaesthetics. The theories of these two philosophers support the main idea of this thesis, namely that dynamic movements of the body can bring aesthetic experiences to their actor. Thus, some of the reasons that explain the attractiveness of this modern sport come to light that are not apparent at first glance.

Impact of Toll-like receptor 4 polymorphism on pro-inflammatory responsiveness in great tit (Parus major)
Vinklerová, Jitka ; Bryja, Josef (advisor) ; Černý, Jan (referee)
Toll-like receptor 4 (TLR4) belongs among chief bacteria-sensing Pattern recognition receptors. Endotoxin (lipopolysaccharide, LPS) recognition by TLR4 triggers signalling leading to release of cytokines that direct leukocyte infiltration into the inflammatory site and cause swelling. Effector mechanisms that ensure pathogen elimination include phagocytosis and oxidative burst. It has been repeatedly reported that the polymorphism in TLR4 may affect host resistance to various diseases. TLR4 may be, therefore, an important molecule in host-parasite co-evolution. Herein, I focused on TLR4 amino acid substitution Q549R which is associated with ornamentation in great tits. In tits I describe immune responsiveness to LPS stimulation on morphological and molecular level and examine effects of the Q549R substitution on inflammation and general body condition. In LPS- treated individuals I found decrease in heterophil-lymphocyte ratio (H/L) that might be caused by attraction of the blood-borne cells into the inflamed tissue. This is in striking contrast with increase in H/L in PBS-treated animals resulting from the stress response. There was no effect of Q549R on general condition and haematological parameters but I revealed a significant effect of the interaction between host Q549R genotype and the type...

Immunogenetic and hormonal markers of predisposition to systemic rheumatic diseases particularly systemic lupus erythematosus
Fojtíková, Markéta ; Pavelka, Karel (advisor) ; Hrnčíř, Zbyněk (referee) ; Rovenský, Jozef (referee)
Fojtikova 2011 INTRODUCTION: Several factors like genetic susceptibility is required for systemic rheumatic diseases development. Immunomodulatory PRL effect supports autoimmunity. AIMS: 1. To detect the immunogenetic background (alleles HLA class I, II and microsatellite polymorphism of the transmembrane part exon 5 of MIC-A gene) of SLE and PsA. 2. To detect PRL serum and synovial fluid with regard to clinical and laboratory RA activity. 3. To find the role of the functional polymorphism -1149G/T SNP PRL of extrapituitary promoter of PRL gene in SLE, RA, PsA, SSc and inflammatory myopathies development. METHODS: Genetic analyses of pateints with SLE (n=156), RA (n=173), PsA (n=100), SSc (n=75), PM (n=47) a DM (n=68) and 123 healthy individuals: PCR-SSP (HLA clase I and II), PCR-fragment analysis (MIC-A) a PCR-RFLP (-1149 G/T SNP PRL). In 29 RA a 26 OA PRL serum and synovial fluid concentrations were detected using immunoradiometric assay. RESULTS: 1. The allele HLA-DRB1*03 (pc=0.008; OR 2.5) and haplotype HLA-DRB1*03-DQB1*0201 (pc <0.001; OR 4.54) were determined as risk immunogenetic markers for SLE in Czech population. In SLE versus controls allele MIC-A5.1 was increased (pc =0.005; OR 1.88). MIC-A5.1 together with HLA-DRB1*03 increases the risk for SLE development, pc <0.000001; OR 9.71....
